PAS-C01 Migration Practice Question
A company is migrating an SAP HANA database from on-premises to AWS. The current system uses 8 TB of data. The migration must be completed within a 4-hour downtime window. The network link has 1 Gbps throughput. What is the MOST efficient migration strategy?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Snowball Edge to transfer the data offline
At 1 Gbps, transferring 8 TB over the network would take approximately 18 hours (8 TB * 1024 GB/TB * 8 bits/byte / 1 Gbps = 65536 seconds = ~18 hours), exceeding the 4-hour window. AWS Snowball Edge (Option D) can transport 8 TB offline, avoiding the bandwidth constraint. Option A (AWS DMS) would not meet the time constraint. Option B (Direct Connect) still has the same bandwidth limitation. Option C (AWS MGN) is for server migration, not database migration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Database Migration Service (DMS) with ongoing replication
Why it's wrong here
DMS would not complete the initial load within 4 hours due to bandwidth.
- ✗
Use AWS Direct Connect to increase bandwidth
Why it's wrong here
Direct Connect does not increase bandwidth beyond 1 Gbps without additional cost and still may not meet time.
- ✗
Use AWS Application Migration Service (MGN)
Why it's wrong here
MGN is for server migration, not database migration.
- ✓
Use AWS Snowball Edge to transfer the data offline
Why this is correct
Snowball Edge can transfer 8 TB offline within the required time.
